INK-SAVING ATTACHMENT FOR EMBOSSING-PRESSES.

Specification of Letters Patent.

Patented Sept. 12, 1916.

Application filed August 10, 1915. Serial No. 44,716.

T 0 all whom it may concern Be it known that I, CLYDE T. DEAN, citi- Zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ink-Saving Attachments for Embossing-Presses, of which the following is a specification.

The present invention relates to an ink saving attachment for embossing presses in which the surplus ink is wiped from the die or printing surface by a strip of paper preparatory to making each impression, the object of the invention being to provide novel and effective means for recovering a large portion of the ink from the wiping strip so as to prevent the waste thereof.

Further objects of the invention are to provide an ink saving attachment of this character which is comparatively simple and inexpensive in construction, which can be readily mounted upon the ordinary embossing press without necessitating any changes or alterations in the construction thereof, which will effectively soften and recover a large portion of the ink which would otherwise be wasted, and which will scrape the ink from the wiping strip without tearing or rupturing the same.

Nith these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description procoeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a rear elevation of the ink saving attachment, showing the same as mounted in position between the side plates of an embossing press. Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1. Fig. 3 is an enlarged detail view of an end portion of the device, portions being broken away and shown in section to illustrate more clearly the details of construction. Fig. 4 is a detail perspective view of one end of the solvent receiving trough, showing the manner of supporting the same.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same referencecharacters.

i For the purpose of illustration the invention 1s shown as mounted upon an embossing press of which fragmentary portions are shown, the numerals 1 designating the side plates of the supporting frame thereof. The wiping web 2 is mounted to be moved through the embossing press in the usual manner, being unwound from a suitable feed roll and finally wound upon a suitable waste roll 3. The wiping strip is employed for removing surplus ink from the face of the die or cleaning surface, and is moved through the machine with an intermittent movement so that fresh portions of the wiping strip are brought sucessively into engagement with the die or printing surface. A considerable amount of ink is ordinarily removed from the die by this wiping strip, and this ink has heretofore been a total loss.

The supporting frame A of the ink saving attachment is shown as having a substantially U-shaped formation, including a horizontal cross bar 4, vertical side pieces 5, and horizontal supporting arms 6 projecting laterally in opposite directions from the up per ends of the side pieecs 5 and engaging the side members 1 of the frame of the embossing press. Collars 7 are mounted upon the arms 6 so as to be susceptible of having a rotary movement thereon, although set screws 8 are provided for clamping the collars in an adjusted position. Rigid with each of the collars 7 and projecting later ally therefrom is a supporting arm 9 which is provided at its free end with a notch or recess 10, said notches 10 being adapted to receive lugs 14" upon the ends of a solvent receiving trough 14 to removably support the same. This trough 14 is provided at its ends near the top thereof with recesses 14 which open at the top of the trough, said recesses serving as bearings for the shaft 11 of a solvent distributing roller 12. With this construction the trough may be readily removed from its support and the roller 12 may be easily removed from the trough when desired, by merely lifting the lugs 14 and shaft 11 from the respective recesses 10 and 14*. This roller 12 is partially submerged in a suitable solvent 13 such as benzin which is held within the trough 14. The wiping strip 2 is carried over the top of the solvent distributing roller 12 with the inky face thereof in engagement with the roller so that solvent will be. applied to the wiping strip in suitable Ila;

quantities for softening the ink thereon as the wiping strip moves rearwardly over the roller 12.

The inner faces of the side pieces5 of the U-shaped supporting frame are provided with vertical guideeways within which the ends of a transversely disposed. knife carrying bar 15 are slidably mounted. Bearings 16 are rcmovably fitted in suitable recesses provided at the upper ends of the side bars 5, said bearings closing the upper ends of the vertical. guideways 17 when in position. Journaled between the two bearings 16 is a shaft 18 upon which a backing roller 19 is keyed or otherwise rigidly applied. This backing roller 19 cooperates with the knife blade 20 upon the yieldably mounted bar 15 to scrape the softened ink from the wiping strip, and a suitable covering 22 of felt or similar material is preferably applied to the periphery of the backing roller.

The knife blade 20 is applied to one side of the knife carrying bar 15, the opposite ends of the said bar 15 being slidably received within the guideways 17, and being engaged by springs 23 which tend to slide the bar upwardly toward the backing roller. The lower ends of the springs 23 are shown as engaged by adjusting screws 2 by means of which the tension in the springs can be increased or decreased, as found most desirable.

After passing over the top of the solvent distributing roller 12 the wiping strip 2 is carried under the backingroller 19 and between the same and the knife blade 20, said knifeblade being arranged in a plane spaced from and parallel to a plane extending through the axis of the backing roller and engaging the backing roller at the side thereof from which the wiping web 2 is drawn. From the scraping blade 20 the -wiping strip 2 is drawn downwardly at a sharp angle and carried under a guide roller 2%. from which it passes upwardly to the waste roll 3. The guide roller 24 may be journaled within suitable ears 25 projecting rearwardly from the side pieces 5 of the supporting frame A.

As the wiping strip 2 moves through the machine it will be employed for removing the surplus from the die or printing surface in the usual manner and be engaged by the ink saving attachment preparatory to being wound upon the waste roll 3. The passage of the strip 2 over the solvent distributing roller 12 will rotate the latter sothat solvent will be fed from the trough 11 to the inky face of the strip in suflicient quantities to soften the ink thereon. The yieldably mounted scraping blade 20 will force the wiping strip into engagement with the back ing roller 19 and cooperate therewith to scrape the previously softened ink from the wiping strip, although the roller 19 will revolve as the wiping strip is advanced, thereby tending to prevent rupture or tearing of the wiping strip. The positioning of the scraping blade 20 in a plane which is spaced from and parallel to a plane passing through the axis of the backingroller 19, and on the side of the roller from which the wiping strip is drawn also tends to reduce liability of tearing or rupturing of the wiping strip. The guide roller 2-l is disposed in such a manner as to cause the wiping strip 2 to be drawn from the edge of the scraping blade 20 at a sharp angle, thereby causing the scraping blade to operate in the most effec-- tive manner to remove the previously softoned ink from the wiping strip. The ink which is thus recovered flows or drops into an inclined chute 26 which is supportei'l upon the lower portion of the main frame A in a position under the scraping blade. From this chute 26 the recovered ink may be caused to flow into any suitable recep tacle.
